"Consider this: Sue, the famous T-Rex that Sotheby's sold back in 1997, was neither prepped nor mounted when she came across the auction block, ultimately realizing a price of more than $8m," adds Herskowitz.

Collectors will also be able to fight over a Tyrannosaurus bataar tooth with an erupting crown at the sale. The 10.5 inch tooth has an $18,000 valuation and is said to be one of the largest from a Tyrannosaurus bataar ever found.

An ankylosaurid skull from a Saichania chulsanensis of the Cretaceous era will also be present at the auction, with a $60,000 estimate.
